These are just samples of the diverse presentations in this dynamic and important field.

A team including Jon Goff of Northrop Grumman Lunar Lander Challenger Masten Space Systems recently submitted a white paper on Depot-Centric Human Spaceflight to the "Review of U.S. Human Space Flight Plans Committee". From the Executive Summary of the paper:

On-orbit storage and transfer of propellants are key capabilities that enable innovative transportation methods for multiple destinations beyond earth orbit, stimulate the commercial spaceflight industry, and allow for sustainable and affordable manned exploration beyond LEO using existing commercial launch vehicles. We find reason to believe that a depot-centric transportation approach will allow NASA’s manned space program to operate in a manner that is exceptionally responsive to the objectives given the Augustine Committee.

Prizes are briefly mentioned in the paper:

A depot-centric transportation network enables and encourages the development of an open architecture—one that multiple commercial and international entities can easily interact with and that is not tied to any one specific destination. ... We can further multiply this effect through the use of prizes and COTS-like programs, as well as more traditional SBIR and Broad Area Announcement solicitations.

Here's some information about the recent Association for Unmanned Vehicle Systems International (AUVSI) Autonomous Underwater Vehicle Competition - which means "no remote controls". The competition was held in San Diego a few days ago.
